MODE(S) FOR CARRYING OUT THE INVENTION

Hereinafter, specific embodiments applying the present technology willbe described in detail with reference to the drawings.

FIG. 1 is a block diagram illustrating an exemplary configuration of anembodiment of a distribution system applying the present technology.

As illustrated in FIG. 1, the distribution system 11 includes aperformer-side information processing device 13, a distribution server14, and N (multiple) viewer-side information processing devices 15-1 to15-N, which are connected to each other via a network 12 such as theInternet.

As discussed later with reference to FIG. 2, the performer-sideinformation processing device 13 continuously transmits a moving imagedepicting the performer to the distribution server 14 via the network12.

The distribution server 14 distributes the moving image transmitted fromthe performer-side information processing device 13 to the viewer-sideinformation processing devices 15-1 to 15-N via the network 12. At thispoint, for example, the distribution server 14 is able to perform imageprocessing of overlaying a flow of comments transmitted from theviewer-side information processing devices 15-1 to 15-N onto thedistributed moving image, and distributing the moving image subjected tosuch image processing.

The viewer-side information processing devices 15-1 to 15-N display amoving image distributed from the distribution server 14 via the network12, enabling a viewer to view the moving image. Additionally, theviewer-side information processing devices 15-1 to 15-N transmit, to thedistribution server 14, information such as comments input by eachviewer in response to the moving image. Subsequently, these comments aretransmitted to the performer-side information processing device 13 viathe distribution server 14.

In the distribution system 11 configured in this way, the performer-sideinformation processing device 13 is able to modify an effect (stageeffect) with respect to the distributed moving image, on the basis ofthe comments input by viewers in response to the moving image.Consequently, it is possible to distribute a moving image with improvedentertainment value, in which the performer and viewers become excitedtogether.

Next, FIG. 2 is a block diagram illustrating a first exemplaryconfiguration of the performer-side information processing device 13.

As illustrated in FIG. 2, the performer-side information processingdevice 13 is equipped with a communication unit 21, an imaging unit 22,a display unit 23, a storage unit 24, and an image processing unit 25.

The communication unit 21 conducts communication via the network 12 inFIG. 1. For example, the communication unit 21 transmits a moving imagesubjected to image processing in the image processing unit 25 to thedistribution server 14. Additionally, the communication unit 21 acquirescomments transmitted from the viewer-side information processing devices15-1 to 15-N, and supplies the comments to the image processing unit 25as viewer input information. Note that the following describes commentsas viewer input information, but besides textual information such ascomments, information such as viewer speech information and facialexpressions, or the number and speed of operations performed on anoperating device of the viewer-side information processing device 15(for example, the number or speed of key presses on a keyboard) may alsobe used as the viewer input information.

The imaging unit 22 includes components such as an image sensor and anoptical lens, for example, and supplies to the image processing unit 25a moving image depicting one or multiple performers as the photographicsubject. Additionally, the imaging unit 22 is able to supply the imagedmoving image to the display unit 23, and cause the display unit 23 todisplay a moving image not subjected to image processing by the imageprocessing unit 25.

The display unit 23 is made up of a liquid crystal display or an organicelectroluminescence (EL) display, for example, and displays images suchas a moving image subjected to image processing by the image processingunit 25, or a moving image imaged by the imaging unit 22. Also, thedisplay unit 23 is able to display a moving image which is supplied fromthe distribution server 14 via the communication unit 21, and which hasbeen subjected to image processing (overlaid with comments) in thedistribution server 14.

The storage unit 24 includes components such as a hard disk drive orsemiconductor memory, and stores information such as images requiredwhen the image processing unit 25 performs image processing.

The image processing unit 25 recognizes viewer emotion on the basis ofviewer input information supplied from the communication unit 21, andperforms image processing that adds a specific effect consistent withthe emotion to the moving image imaged by the imaging unit 22.Subsequently, the image processing unit 25 supplies the moving imagewith the added specific effect that is consistent with the vieweremotion to the display unit 23 for display, and also causes the movingimage with the added effect to be transmitted to the distribution server14 via the communication unit 21.

In addition, as illustrated in FIG. 2, the image processing unit 25includes a viewer information acquisition unit 31, a viewer emotionrecognition unit 32, an emotion effect selection unit 33, a backgroundeffect drawing unit 34, and a face effect drawing unit 35.

The viewer information acquisition unit 31 acquires comments from theviewer-side information processing devices 15-1 to 15-N supplied fromthe communication unit 21 as viewer information, and supplies the viewerinformation to the viewer emotion recognition unit 32.

The viewer emotion recognition unit 32 recognizes viewer emotion, on thebasis of viewer information supplied from the viewer informationacquisition unit 31. For example, the viewer emotion recognition unit 32is able to recognize viewer emotion in accordance with an emotionclassification (the Russell circumplex model of emotion) in whichvarious emotions are classified as illustrated in FIG. 3.

For example, the viewer emotion recognition unit 32 stores in advance alarge number of comments anticipated to be used as viewer information,and for these comments, associates a level indicating a high or lowdegree of arousal as well as a level indicating the pleasantness orunpleasantness of the emotion. Subsequently, the viewer emotionrecognition unit 32 computes a distribution of comments in accordancewith the level indicating the high or low degree of arousal as well asthe level indicating the pleasantness or unpleasantness of the emotionassociated the comments supplied from the viewer information acquisitionunit 31, and recognizes the emotion classified at a position where acertain prescribed number of comments or more are distributed as theviewer emotion.

The emotion effect selection unit 33 selects an emotion affect inaccordance with the viewer emotion recognized by the viewer emotionrecognition unit 32 from among multiple emotion effects stored in thestorage unit 24, and controls the addition of the effect with respect tothe moving image. For example, in the storage unit 24, emotions to berecognized in the viewer emotion recognition unit 32 are associated withemotion effects, that is, images imparting an effect consistent with theassociated emotion, and the emotion effect selection unit 33 is able toselect an emotion effect in accordance with the correspondencerelationship.

Additionally, an emotion effect includes a background effect displayedbehind a performer depicted in the moving image, and a face effectdisplayed overlaid onto a viewer face depicted in the moving image.Consequently, the emotion effect selection unit 33 supplies thebackground effect drawing unit 34 with a background effect selected inaccordance with the viewer emotion recognized by the viewer emotionrecognition unit 32, and supplies the face effect drawing unit 35 with asimilarly selected face effect.

The background effect drawing unit 34 performs image processing ofcutting out a performer depicted in the moving image imaged by theimaging unit 22, and drawing a moving image in which the backgroundeffect supplied from the emotion effect selection unit 33 is compositedbehind the performer. Subsequently, the background effect drawing unit34 supplies the face effect drawing unit 35 with the moving image inwhich the background effect is composited behind the performer.

The face effect drawing unit 35 conducts a face recognition process thatrecognizes the face of a performer depicted in the moving image suppliedfrom the background effect drawing unit 34, and in accordance with theposition and size of the face, adjusts the position and size of a faceeffect supplied from the emotion effect selection unit 33. Furthermore,the face effect drawing unit 35 conducts image processing that draws amoving image in which the position- and size-adjusted face effect iscomposited in the foreground of the moving image from the backgroundeffect drawing unit 34. Subsequently, the face effect drawing unit 35supplies the moving image in which the background effect is compositedbehind the performer and the face effect is composited in front of theperformer's face to the display unit 23 for display, and also causes thecomposited moving image to be transmitted to the distribution server 14via the communication unit 21.

Since the performer-side information processing device 13 is configuredas above and an emotion effect consistent with the viewer emotion may beselected, the sense of unity between a performer and a viewer may beenhanced.

Specifically, the distribution system 11 is able to distribute not amoving image of the related art as illustrated on the left side of FIG.4, namely a moving image overlaid with a flow of comments from viewers,but instead a moving image as illustrated on the right side of FIG. 4,namely a moving image in which is drawn a background effect (an image ofburning flames) that is consistent with a viewer emotion recognized onthe basis of a large number of praising comments. In this way, bycausing the viewer emotion to be reflected in the moving image, thesense of unity between a performer and a viewer may be enhanced.

Next, FIG. 5 is a flowchart explaining image processing conducted in theimage processing unit 25.

For example, a process is started when the performer performs anoperation to start the distribution of a moving image from theperformer-side information processing device 13. In step S11, the viewerinformation acquisition unit 31 acquires comments from the viewer-sideinformation processing devices 15-1 to 15-N supplied from thecommunication unit 21 as viewer information, and supplies the viewerinformation to the viewer emotion recognition unit 32.

In step S12, the viewer emotion recognition unit 32 recognizes vieweremotion, on the basis of the viewer information supplied from the viewerinformation acquisition unit 31 in step S11.

In step S13, the viewer emotion recognition unit 32 determines whetheror not the number of comments classified under any one emotionrecognized in step S12 has become equal to or greater than a prescribedvalue. In step S13, if the viewer emotion recognition unit 32 determinesthat the number of comments classified under any one emotion has notbecome equal to or greater than the prescribed value, the processreturns to step S11, and thereafter, a similar process is repeated.

On the other hand, if the viewer emotion recognition unit 32 determinesthat the number of comments classified under any one emotion has becomeequal to or greater than the prescribed value, the process proceeds tostep S14. In this case, the viewer emotion recognition unit 32recognizes the emotion equal to or greater than the prescribed value asviewer information, and supplies the viewer information to the emotioneffect selection unit 33.

In step S14, the emotion effect selection unit 33 selects an emotionaffect in accordance with the viewer emotion recognized by the vieweremotion recognition unit 32 from among multiple emotion effects storedin the storage unit 24. Subsequently, the emotion effect selection unit33 supplies the background effect drawing unit 34 with the backgroundeffect of the selected emotion effect, while also supplying the faceeffect drawing unit 35 with the face effect.

In step S15, the background effect drawing unit 34 draws a moving imagein which the background effect supplied from the emotion effectselection unit 33 in step S14 is composited behind the performer imagedby the imaging unit 22, and supplies the moving image to the face effectdrawing unit 35.

In step S16, the face effect drawing unit 35 draws a moving image inwhich the face effect supplied from the emotion effect selection unit 33in step S14 is composited in front of the face in the moving imagesupplied from the background effect drawing unit 34 in step S5.Subsequently, the face effect drawing unit 35 supplies the moving imageto the display unit 23 for display while also transmitting the movingimage to the distribution server 14 via the communication unit 21. Afterthat, the process returns to step S11, and thereafter, a similar processis repeated.

Next, FIG. 6 is a block diagram illustrating a second exemplaryconfiguration of the performer-side information processing device 13.

In the performer-side information processing device 13A illustrated inFIG. 6, the same signs are used to denote the configuration shared incommon with the performer-side information processing device 13 in FIG.2, and detailed description thereof will be reduced or omitted. Namely,the performer-side information processing device 13A is equipped withthe communication unit 21, the imaging unit 22, the display unit 23, andthe storage unit 24, in common with the performer-side informationprocessing device 13 in FIG. 2.

Meanwhile, the performer-side information processing device 13A has adifferent configuration from the performer-side information processingdevice 13 in FIG. 2 by being equipped with an input unit 26, while theimage processing unit 25A includes, in addition to the viewerinformation acquisition unit 31, the viewer emotion recognition unit 32,the emotion effect selection unit 33, the background effect drawing unit34, and the face effect drawing unit 35, a performer emotion recognitionunit 36.

The input unit 26 is made up of components such as a keyboard, amicrophone, or an imaging device, for example, and acquires informationsuch as comments input by the performer, speech spoken by the performer,and the performer's facial expressions as performer information, andsupplies the performer information to the performer emotion recognitionunit 36 of the image processing unit 25A.

The performer emotion recognition unit 36 recognizes a performer emotionon the basis of the performer information supplied from the input unit26, and supplies the recognized performer emotion to the emotion effectselection unit 33.

In the performer-side information processing device 13A configured inthis way, the emotion effect selection unit 33 is able to select anemotion effect on the basis of both viewer emotion and performeremotion. Consequently, for example, when the viewer emotion and theperformer emotion match, the emotion effect selection unit 33 is able toselect an emotion effect with a bigger effect. As a result, the sense ofunity between a performer and a viewer may be enhanced further. Notethat the emotion effect selection unit 33 may also select an emotioneffect on the basis of just the performer emotion.

Also, since the performer-side information processing device 13A usesperformer emotion, when the performer does not want to generateexcitement, for example, the performer emotion does not match withteasing comments input by a viewer, and thus it is possible to keep theviewer emotion from being reflected. In other words, in the case ofselecting an emotion effect from just the viewer emotion, an emotioneffect that imparts an exciting effect may be selected accidentally evenfor teasing comments input by a viewer, and thus expressing excitementand emotion interactively has been difficult.

Specifically, when the performer is singing, comments of applause inputby a viewer before or partway through the chorus of the sing may be“teasing”. In contrast, comments of applause input by a viewerimmediately after the performer finishes singing the chorus express“inspiration”. In this way, by recognizing the state of the performer onthe basis of input from the performer (in the case of a song, theperformer's voice), it is possible to select an emotion effect thatimparts an effect more consistent with the situation.

Furthermore, for example, emotions and facial expressions that expressthe performer's level of excitement may be input, and the performer-sideinformation processing device 13A may determine whether or not commentsfrom viewers are input in correspondence with the progression ofexcitement in the performer's emotions and facial expressions, andthereby generate further excitement in the performance at that moment.

Note that besides comments, information such as a viewer's speech orsound pressure, heart rate, and facial expressions may also be used asviewer information, for example, and viewer emotion may be estimatedaccurately on the basis of these multiple types of viewer information.Additionally, an overall viewer emotion with respect to a moving imagemay be estimated on the basis of the viewer information for multiplepeople.

As an example, FIG. 7 will be referenced to describe an example ofselecting a background effect on the basis of the intensity of viewerlaughter in the performer-side information processing device 13.

For example, in the distribution system 11, viewer laughter computed byimaging viewers with an imaging device provided in the viewer-sideinformation processing devices 15-1 to 15-N may be transmitted.Subsequently, in the performer-side information processing device 13,the viewer information acquisition unit 31 acquires the laughtertransmitted from the viewer-side information processing devices 15-1 to15-N as viewer information, and the emotion effect selection unit 33selects a background effect on the basis of the intensity of the viewerlaughter.

Specifically, the emotion effect selection unit 33 makes a determinationin accordance with the intensity of viewer laughter. For example, asillustrated in FIG. 7, even if the performer makes the same funny face,a background effect that generates excitement is selected if theintensity of viewer laughter is high, whereas a background effect thatcasts a chill over the situation is selected if the intensity of viewerlaughter is low. Furthermore, the emotion effect selection unit 33 mayalso display effect text in accordance with the intensity of viewerlaughter, in which effect text that generates excitement is displayed ifthe intensity of viewer laughter is high, whereas effect text that castsa chill over the situation is displayed if the intensity of viewerlaughter is low.

In this way, in the performer-side information processing device 13, itis possible to select a more optimal background effect on the basis ofnot only recognizing viewer emotion, but also on the basis of theintensity of viewer laughter. Note that besides the intensity oflaughter, information such as the duration of laughter, the number oflaughing viewers, the loudness of the laughter, and comments suppliedtogether with laughter may also be used to make a laughterdetermination. For example, in the case in which the viewer informationincludes information indicating that a viewer is laughing, the emotioneffect selection unit 33 may select an effect with a more fun result ifthe viewer laughs for a long time on the basis of the information.Additionally, in the performer-side information processing device 13,the manner of the background effect may be modified in accordance withthe properties of the laughter, such as a sudden unexpected laugh or aloud burst of laughter, for example.

Next, FIG. 8 will be referenced to describe an interaction usingperformer and viewer heart rates in the performer-side informationprocessing device 13A.

For example, in the distribution system 11, the heart rates of viewersmay be acquired and transmitted by a heart rate sensor provided in theviewer-side information processing devices 15-1 to 15-N. Similarly, theperformer-side information processing device 13A is able to acquire theheart rate of the performer with the input unit 26 (for example, anarmband-style or ear clip-style heart rate meter). As another example, aviewer or the performer may be imaged by an imaging device, and theheart rate may be computed from the image.

FIG. 8 illustrates an example of distributing a game screen from a gamethat the performer is playing, in which a performer avatar is displayedin the lower-left of the game screen, and a meter based on heart rate isdisplayed in the upper-left of the game screen. This meter is based onboth the heart rates of viewers and the heart rate of the performer, andas the variation in these heart rates become more in tune with eachother, an effect expressing greater empathy is displayed.

For example, if the level of excitement and empathy between performerand viewer becomes equal to or greater than a prescribed value, theeffect becomes one in which a heartbeat mark displayed on the meterthrobs greatly. Additionally, if the heart rate is designed to be linkedto the control of the game, a special attack may be produced when thelevel of excitement and empathy between performer and viewer becomesequal to or greater than a prescribed value. Also, a change may beproduced in the performer avatar displayed in the lower-left of the gamescreen.

In this way, in the performer-side information processing device 13A,the interactivity between performer and viewer may be enhanced further,on the basis of not only recognizing performer and viewer emotion, butalso the level of excitement and empathy between performer and viewercomputed from heart rates. Note that besides the heart rate of a viewer,information such as a face image, speech, sound pressure, or buttontapping may also be used as viewer information from which the level ofexcitement may be acquired.

Note that the foregoing embodiments describe effects drawn onto a movingimage, but besides visual effects, the performer-side informationprocessing device 13A may also distribute sound effects based onperformer and viewer emotion together with a moving image, for example,and add various other types of effects. Additionally, the performer-sideinformation processing device 13A may display an object based onperformer and viewer emotion (for example, a stamp or balloon) in themoving image. These object-based effects may be added withoutdistinguishing between performer and background, and may be compositedin the foreground in a portion other than the performer's face, forexample. Furthermore, the performer-side information processing device13A may also forcibly end distribution of a moving image if a levelindicating the degree of viewer arousal falls, or if a level indicatingthe degree of unpleasant viewer emotion rises, for example.

In addition, the performer-side information processing device 13 maychange an effect drawn onto a moving image depending on not only vieweremotion, but also the number of viewers. If the number of viewersreaches a fixed number or more, the performer-side informationprocessing device 13 may change to a flashier effect, whereas if thenumber of viewers is extremely small, the performer-side informationprocessing device 13 may remove the effect. Additionally, theperformer-side information processing device 13 may also add a specificeffect, change an added effect, or remove an added effect in accordancewith the number of times specific viewer information is input frommultiple viewers, such as the number of times a specific comment meaning“laughter” or “applause” is input, for example. Furthermore, theperformer-side information processing device 13A may also be configuredto distribute a moving image in which a special effect is drawn only forviewers who input viewer information more actively. In other words,instead of distributing the same moving image to all viewers, the effectin the moving image distributed to each viewer may be changed inaccordance with the viewer's reaction.

Furthermore, the present embodiment describes an example in which theprocess of adding an effect is conducted in the performer-sideinformation processing device 13, but the performer-side informationprocessing device 13 may conduct just a process of transmitting a movingimage of the performer, and the process of adding an effect on the basisof viewer information may be conducted in the distribution server 14,for example. Alternatively, the process may be divided up between theperformer-side information processing device 13 and the distributionserver 14.

It should be noted that each process described referring to theflowchart above includes a process that is not necessarily performed ina time series manner in the order described in the flowchart, but may beperformed in a parallel or individual manner (for example, a paralleledprocess or a process by objects). In addition, the program may beprocessed by one CPU, or processed by a plurality of CPUs in adistributed manner.

The above-described series of processing (an information processingmethod) may be performed by hardware or may be performed by software.When the series of processing is performed by software, a programforming the software is installed into a computer that is incorporatedin a dedicated hardware, or installed from a program storage medium onwhich programs are recorded into a general-purpose personal computer,for example, that can perform various types of functions by installingvarious types of programs.

FIG. 9 is a block diagram illustrating an exemplary hardwareconfiguration of a computer that executes the foregoing series ofoperations according to a program.

In the computer, a central processing unit (CPU) 101, read-only memory(ROM) 102, and random access memory (RAM) 103 are connected to eachother by a bus 104.

Additionally, an input/output interface 105 is connected to the bus 104.Connected to the input/output interface 105 are an input unit 106 thatmay include devices such as a keyboard, mouse, and microphone, an outputunit 107 that may include devices such as a display and one or morespeakers, a storage unit 108 that may include devices such as a harddisk and non-volatile memory, a communication unit 109 that may includea device such as a network interface, and a drive 110 that drives aremovable medium 111 such as a magnetic disk, optical disc,magneto-optical disc, or semiconductor memory.

In a computer configured as above, the foregoing series of operationsare conducted due to the CPU 101 loading a program stored in the storageunit 108 into the RAM 103 via the input/output interface 105 and the bus104, and executing the program, for example.

The program executed by the computer (CPU 101) may be provided by beingrecorded onto the removable medium 111 as an instance of packaged mediasuch as magnetic disks (including flexible disks), optical discs(including Compact Disc—Read-Only Memory (CD-ROM) and Digital VersatileDisc (DVD)), magneto-optical discs, or semiconductor memory.Alternatively, the program may be provided via a wired or wirelesstransmission medium such as a local area network, the Internet, orsatellite broadcasting.

Additionally, the program may be installed to the storage unit 108 viathe input/output interface 105 by inserting the removable medium 111into the drive 110. The program may also be received by thecommunication unit 109 via a wired or wireless transmission medium, andinstalled to the storage unit 108. Otherwise, the program may bepreinstalled in the ROM 102 or the storage unit 108.
